Update (Oct 28):
on October 28 the federal German government has enacted a new lockdown
and tightened restrictions pertaining to travel and meetings.
In view of these developments, we must conclude at this time that the
symposium is no longer viable and, with deep regret, we are forced to call
it off. We are grateful to all of you who have steadfastly supported the
symposium despite these difficult times.

November 2-6, 2020 at Physikzentrum Bad Honnef,
If you come from a risk-areas country (1), you must present
a medical certificate, which must not be older than 48 hours.
The 48-hour period begins at the time the test result is
approved and ends at the time of entry into the Federal
Republic of Germany.
In the current regulation of the state of North
Rhine-Westphalia - the location oft he Physikzentrum - there is
no regulation for travelers from no-risk-areas countries or
inner-German risk areas.
The hygiene concept of the Physikzentrum has been practiced
since July and has proven itself. The short version: compulsory
masks everywhere except in the lecture hall and at the dining
table. For more details see the file attached. All participants
are accommodated in single rooms, unless a double room is

How to sign up?
In addition to a conference room, the Physics
Center Bad Honnef offers an infrastructure for up to 80
guests, that means for all our participants

The symposium room in the conference venue will
be equipped with a Computer (Windows;VGA), LCD
projector, laser pointer and microphone.
Poster size should be A0 (portrait, i.e.,

Topic of the IUTAM symposium is the computational
prediction of damage, crack growth, and the extent of
fragmentation in solids.
Recently, research in computational fracture mechanics
has advanced remarkably, typically using cohesive zone
models and extended finite elements. Beyond these well
established and popular methods, several innovative
approaches have emerged, such as phase field methods,
eigenfracture, eigenerosion, and level-set methods. These
approaches are characterized by a regularization of the
evolving crack boundaries with an additional small but
finite length scale. This length scale arouses new
questions and doubts, in particular concerning multi-physic
The aim of the IUTAM symposium is to draw a comparative
overview of different computational strategies for
multi-field fracture problems by illustrating the most
innovative -non necessarily the nowadays most popular-
techniques. We would like to open a forum to discuss new
horizons of multi-field fracture mechanics covering several
aspects of research on computational fracture, starting
from specific methods of choice and numerical strategies to
theoretical aspects of constitutive modeling in a
multi-field setting. Particular emphasis will be laid on
pioneering discretization methods for the solution of
coupled non-linear problems at different length-scales.
The participation at the IUTAM Symposia is by invitation
from the Scientific committee only.
Phase field models have been in the focus of research in
applied mathematics and mechanics in recent years. Due to the
multiple applications in coupled problems, phase transitions,
and fracture the GAMM activity group on Phase field modelling
was installed at the annual GAMM meeting 2013, in Novi Sad,
Serbia. The intention of the activity group is to bring
together expertise from mathematics, mechanics and materials
science, to improve the understanding of phase field
approaches, to analyse the models analytically, and to devellop
improved numerical schemes.
The activity started its actvity in the summer of 2013 with a
kick-off meeting in Frankfurt.

2014: IUTAM Symposium on innovative numerical approaches for materials and structures in multi-field and multi-scale problems
September 1-4, 2014 at Burg Schnellenberg near Cologne
(North Rhine-Westphalia, Germany)
We thank all the participants for their valuable
contributions. The friendship and fellow-feeling felt during
the symposium inspired the idea to collect the presentations of
some of the present researchers in a special book. Our choice
was to organize a book as part of the series Lecture Notes
in Applied and Computational Mechanics (LNACM), entitled
Innovative Numerical Approaces for Multi-Field and
Multi-Scale Problems. It will appear at Springer in July

How to get there?
The venue is a Castle and can be
reached at best by car. Next regional train station is
Finnentrop. Main train stations nearby are Cologne,
Dortmund or Hagen. The next airports are Cologne Bonn
Airport and Frankfurt Airport. Neither from Cologne nor
from Frankfurt to Attendorn are direct train or bus
connections. There will be, of course, taxis. We think to
organize a 'shuttle service' in a sense, that we pre-book a
taxi or minibus which collects several people of the
symposium to share the costs. If you are interested, please
send us your time of arrival at:
If you prefer to go by train, you may find connections
at bahn.de; we would recommend to go to
Finnetrop and then take a taxi.
If type into google maps 'Burghotel Schnellenberg' you
find a map of the location.
Some more details:
The symposium room in the conference venue will be
equipped with a Computer (Windows;VGA), LCD projector,
laser pointer and microphone.
Poster size should be A0 (portrait, i.e., 84x119cm) or
any other format with at most 90cm width.
A get together with medieval music and a corresponding
meal is planned in the evening of Tuesday September 2nd,
opened to all symposium participants.
We thank our colleagues who accepted to attend the IUTAM on
the occasion of M.Ortiz’ 60th birthday. For an enjoyable stay
we ask you for an "all inclusive" conference fee. The
fee includes symposium material, lodging with full meals at the
castle Burg Schnellenberg, a featured Medieval Social Event,
and a book of Abstracts of the symposium contributions.
